The Cool Fat Burner is proven to work by many mechanisms beyond just brown fat activation, such as skeletal muscle uncoupling, adiponectin release, and general thermal loading.
In addition, the Cool Fat Burner can help you grow and increase brown fat, even if you start with none!
Look at how CFB creator Eric was built before he used the Cool Fat Burner. Look at how much brown fat he had after using the CFB and getting fit (massive amounts, despite being 40 yrs old). Look at how Eric maintained maximal BAT levels, even through the hot summer weather! With the Cool Fat Burner you can grow more BAT.
